While the Casa Batlló is located in Barcelona, Spain there are many other places in Spain, some by Gaudi, that the punch bowl could be located. Spain seems to be an ideal home for this punch bowl.
compare: Much like the Lidded Punch Bowl and Ladle, Leah’s Mantel Clock is a decorative Art Nouveau piece that serves as decoration as well as serving a purpose. Both have free flowing curves and can be located in any home to add some interest.
contrast: Jacques-Emile Ruhlmann's dressing table is placed in Southern California which is not a likely place for an Art Nouveau punch bowl.
